Abstract
A rotary compressor () includes a closed casing (), a cylinder (), a piston (), a lower bearing member (), a vane (), a suction port (), a discharge port (), and a partition member (). The partition member () is attached to the lower bearing member () so as to form a refrigerant discharge space () serving as a flow path of a refrigerant discharged from a discharge chamber () through the discharge port (). The lower bearing member () is provided with a first recess () on the same side as the suction port () with respect to a reference plane, the reference plane being a plane including a central axis of the cylinder () and a center of the vane () when the vane () protrudes maximally toward the central axis of the cylinder (). A portion of oil stored in an oil reservoir () flows into the first recess (), and thereby an oil retaining portion () is formed.
